Actually, aside from many backports and hacks, there are just three
interesting patch series from my point of view:

http://marc.info/?l=xen-devel&m=133001901013674&w=2 xen/arm: receive Xen events and initialize xenbus
http://marc.info/?l=xen-devel&m=134038186610813&w=2 xen/arm: PV console support
http://marc.info/?l=xen-devel&m=134140081408627&w=2 xen/arm: grant_table, blkfront and blkback

The last two are recent and I have received feedback from you on the second
one.

Good idea, but fortunately there aren't that many of them.
In fact if we exclude the ones that just add more #include, these are the ones
that remains:

d122a6b075e582af17dd2b3ddd8ee4ded3f85300 xen/arm: receive xen events on arm
1902bd5574447c03c1e6081cce98d8bf6e1f35e7 xen/arm: compile and run xenbus
5bbda4a165284aceee19b54954f10344b724b506 xen/arm: enable evtchn irqs
d4fda31cf5411e8ada3f1163c68595b7474d7c1d xen/arm: initialize grant_table on ARM

it would be nice if you could take a look at them and tell me what you think.

Yes, the idea is to post them in a single set.
Now that I have support for the basic functionalities (guests booting, PV
console, disk and network), I can start working on a single patch
series for a recent kernel.
